Correct answer: "tiny hairlike structures that help in movement of some cells."
Explanation, briefly:
- Eukaryotic cilia are slender, hair‑like surface projections covered by the plasma membrane and built on an axoneme of microtubules (typically a 9+2 arrangement). They move whole cells or move fluid/particles along cell surfaces.
- "Long whip‑like tails" describes flagella (eukaryotic flagella or bacterial flagella), not cilia.
- They are not usually described as "thick membrane‑bound organelles" — they are membrane‑bound extensions of the cell surface with a microtubular core.
